Objective To evaluate the impact of hepatitis B e antigen (HBeAg) states and hepatitis B virus DNA loads on the prognosis of chronic severe hepatitis B.Methods A total of 406 hospitalized patients with chronic severe hepatitis B in Nanfang Hospital of Southern Medical University from January 2002 to December 2007 were retrospectively analyzed.The impact of HBeAg states and HBV DNA loads on the prognosis was evaluated.The measurement data were compared by t test and rates were compared by chi square test.Results Of all the 406 patients with chronic severe hepatitis B,208 (51.2%) patients were HBeAg-positive and the remaining 198 (48.8%) were HBeAgnegative.There was no significant difference of constituent ratio of male and female,average peak value of total bilirubin and average valley value of prothrombin activity between HBeAg-positive group and HBeAgnegative group.However,the average age of HBeAg-negative patients was (46.7±12.8) years old,which was significantly higher than that (38.3±13.5) years old in HBeAg-positive group (t = 6.43,P＜0.01 )the proportion of patients with liver cirrhosis in HBeAg-negative group (67.7%) was much higher than that in HBeAg-positive group (45.7%) (X2=19.97,P＜0.01);the improved rate in HBeAg-negative group (32.3%) was significant lower than that in HBcAg-positive group (44.7%) (X2=6.56,P＜0.05).Increasing HBV DNA levels was associated with lower improved rate in both 208 HBeAg-positive and 198 HBeAg-negative patients(X2=22.98,26.04,respectively,both P＜0.01 ).Conclusions HBeAg-negative patients with chronic severe hepatitis B has worse prognosis than HBeAg-positive patients;and the prognosis is getting worse with the increasing HBV DNA level regardless of the HBeAg status.

Objective To explore the relationship of insulin resistance with serum 25-hydroxyvitamin D levels and arterial stiffness in elderly patients.Methods A total of 162 elderly inpatients (aged 60 years or over) were recruited from 2012 to 2014.Levels of fasting serum insulin,fasting serum glucose,creatinine and vitamin D were determined.Insulin resistance (IR) was evaluated by the homeostasis model assessment of insulin resistance (HOMA-IR).The patients were divided into the following three groups according to HOMA-IR:the low IR group with HOMA-IR less than 2 (n=78),the median IR group with HOMA-IR between 2 and 6 (n=43),and the high IR group with HOMA-IR greater than 6 (n=41).Arterial stiffness was assessed by carotid-femoral pulse wave velocity (cfPWV).Arterial stiffness and serum vitamin D levels were compared among the three groups.Results cfPWV was increased and the serum 25-hydroxyvitamin D level was decreased in the high insulin resistance group compared with the low insulin resistance group[(13.2± 5.7) μg/L vs.(17.8±6.2) μg/L,(14.3±5.2) m/s vs.(11.9±3.0) m/s].Multiple liner regression analysis showed that IR was negatively correlated with the serum 25 hydroxyvitamin D level (r=-0.63,P＜0.05) and positively correlated with arterial stiffness (r=0.45,P＜0.05) after adjustment for age,sex and other confounders.Conclusions Elderly patients with high insulin resistance may have lower levels of serum vitamin D and higher arterial stiffness.

BmK AngM1 is a long-chain scorpion toxin purified from the venom of Buthus martensii Karsch. It has been reported to exhibit evident analgesic effect and low toxicity, and has the potential to be a novel analgesic drug. The BmKAngM1 gene was transformed into Pichiapastoris GS115. Mut+ and Mut(s) recombinant strains were screened by phenotype and Mut+ recombinant strains were used to detect BmK AngMl gene copy number in the real-time PCR. Expression of BmK AngM1 in the Mut+ recombinant strain was compared with that of the Mut(s) recombinant strain with the same single copy of BmK AngM1 gene under the same condition. The results indicated that the transcription level of BmK AngM1 gene in the Mut(s) recombinant strain was 2.7 fold of that in the Mut recombinant strain in the real-time PCR, and the expression of BmK AngM 1 in the Mut(s) recombinant strain was 1.5 fold of that in the Mut+ recombinant strain. Therefore, Mut(s) recombinant strain showed better ability to express BmK AngM1 than Mut+ recombinant strain.

Codon bias is an important factor which influences heterologous gene expression. Optimizing codon sequence could improve expression level of heterologous gene. In order to improve the expression level of BmK AngM1 gene encoding the analgesic peptide from Buthus martensii Karsch in Pichia pastoris, the codon-optimized BmK AngM1 gene according to its cDNA sequence and the preference codon usage of P. pastoris were cloned into expression vector pPIC9K and then transformed into P. pastoris. The expersion of recombinant BmK AngM1 (rBmK AngM1) was inducced by methanol in the medium, and the expression level of the optimized BmK AngM1 gene was 3.7 times of the native one. These results suggested that the expression of BmK AngM1 in P. pastoris could be successfully improved by codon optimization.

ObjectiveTo evaluate the significance of flexion priority strategy and the principle of joint mobilization technique in the rehabilitation of posttraumatic stiffness of the elbow. Methods24 patients with posttraumatic stiffness of the elbow were divided into 2 groups, 12 patients in each group. The treatment group was treated with flexion priority strategy of joint mobilization technique only in the treatment of flexion contracture. In order to decrease the pain caused by joint mobilization training of extension and achieve the restoration of flexion as early as possible, the rehabilitation of extension was altered to self-exercise under the consultation of doctors combined with gentle passive traction by the therapist. The control group was treated with joint mobilization technique of both flexion and extension once a day. All the patients were measured the flexion range, extension range, and flexion-extension arc after 6 weeks of rehabilitation. Results6 weeks after rehabilitation, the treatment group got 124° of flexion (range 95°～135°), much better than the control group of 95° (range 80°～110°) （P<0.01）. There was no significant difference of extension degrees between the treatment group (15°, range 10°～35°) and the control group (16°, range 10°～30°) （P＞0.05）. The final arc of flexion and extension in the treatment group had an increase of 53°, significantly greater than 30° in the control group（P<0.01）. ConclusionFlexion priority strategy of elbow rehabilitation can significantly restore the flexion function of posttraumatic elbow stiffness.
